Which of the following equations represents a line that is parallel to y=5x-4 and passes through the point, (3,4)?
valkas [14]
Slope of given line = 5

Slope of parallel lines is the same, so slope of the line parallel to the given line will be m = 5

We have the slope and a point, using the point-slope form we can write the equation of the line:

y - 4 =5 (x - 3)

y = 5x - 15 + 4

y = 5x - 11

So, the above equation is the desired answer.

The size of a jar of coffee is increased by one 1/5. The new size is later reduced by 1/5
OlgaM077 [116]

Answer:

The new jar would be smaller than the original.

Step-by-step explanation:

First you would have to find one 1/5 of the original size. This gives you the increased size.

Then, you'd find 1/5 of the new size and subtract it from the increased size of the jar.

1/5 of the increased size is larger than 1/5 of the original size, so no matter what number it is, you'll always end up with a smaller-sized jar of coffee at the end.
